Suikoden and Gravity Daze were big sellers in Japan for the week ending February 12, according to the latest Media Create figures, and while the former provided PSP with a slight boost in sales over the week prior, the later didn’t help Vita sell any extra systems.

Konami made a surprise announcement at a Tokyo Game Show stage event for tri-Ace’s Frontier Gate by disclosing that a new entry in the Suikoden RPG series titled Genso Suikoden Tsumugareshi Hyakunen no Toki is in development for the PSP.
